Overview:

The pneumatic clamp type flange butterfly valve consists of a rubber sealed butterfly valve and a carbon steel or stainless steel valve plate and stem. Suitable for regulating flow and intercepting media on water supply and drainage, gas pipelines with temperatures ≤ 120 ℃ in industries such as textiles, papermaking, food, pharmaceuticals, chemicals, petroleum, electricity, etc.

Adopting a new series of GT type pneumatic actuators, with double acting and single acting (spring reset), gear transmission, safe and reliable; The large-diameter valve adopts a series of AW type pneumatic actuator fork type transmission, with a reasonable structure and large output torque, and is available in double acting and single acting types.

1. Gear type dual piston, with large output torque and small volume.
2. The cylinder is made of aluminum material, which is lightweight and aesthetically pleasing.
3. Manual operating mechanisms can be installed at the top and bottom.
4. The rack and pinion connection can adjust the opening angle and rated flow rate.
5. The actuator can be equipped with live signal feedback indicators and various accessories to achieve automated operation.
6. The IS05211 standard connection provides convenience for the installation and replacement of products.
7. The adjustable screws at both ends provide a ± 4 ° adjustable range for standard products between 0 ° and 90 °. Ensure synchronization accuracy with the valve.
